Oracle Base Database patching to 19.17 using DBCLI

 




OCI - (Oracle Cloud Infrastructure)

Intro

Cloud platforms are booming and many organizations are planning on a cloud journey to get a competitive advantage.  The cloud market is vast, with a diverse selection of services. It's not easy to select a suitable cloud platform for an organization.  There are certain criteria you need to consider when selecting a platform. 

    • Certifications & Standards
    • Technologies & Service Roadmap
    • Data Security, Data Governance, and Business policies
    • Service Dependencies & Partnerships
    • Contracts, Commercials & SLAs
    • Reliability & Performance
    • Migration Support, Vendor Lock-in & Exit Planning
    • Business health & Company profile
    • Cost of the cloud services and License.
    All these factors play a huge role when selecting a cloud platform suited for your system workloads. If your IT infrastructure consists of many Oracle databases,  I would say there is no better place than OCI (Oracle Cloud Infrastructure) to host your workload.  Oracle has been there for the market for a long time and gives immense selection when hosting Oracle workloads. 

    Autonomous selection  :
    • Autonomous Database
    • Autonomous data warehouse
    • Autonomous JSON Database
    • Autonomous Transaction Processing
    Exadata services : 
    • Exadata at Oracle Cloud.
    • Exadata Cloud@Customer
    DB service  selection :
    • Oracle Base Database Service
    VM selection.
    • Bare Metal

    The best part about OCI is they came up with new orchestration tools to standardize and ease the administration work. I have listed down all the orchestration tools and administration work we can perform using the tool.

    • OCI CLI - Oracle Cloud Command Line Interface:
    OCI is a small-footprint tool that makes calls to Oracle Cloud Infrastructure REST APIs using HTTPS requests. It is built with the SDK for Python.
    • dbcli - Database Cli :
    dbcli is a command line tool available on virtual machines and bare metal DB systems (not on Exadata DB systems)
    • cliadm - CLI admin command
    Updates your dbcli tool to get the new commands that support new features added to the cloud services:
    • dbaascli
    dbaasapi is deprecated and replaced by dbaascli. 

    This tool is the command line tool for life-cycle and administration operations for Exadata databases. It must be run on the local Exadata compute node. Many dbaascli commands can be run by the Oracle user. However, some commands require root administrator privileges.

    Summary of the dbaascli tool task ; 
    1. Scale up/down OCPUs in disconnected mode (ExaCC only)
    2. Download and list available software images
    3. Managing pluggable databases (PDBs) – use SQL alternatively
    4. Rotating the TDE master encryption key – use SQL alternatively
    5. Starting and stopping the Oracle Net listener – use lsnrctl alternatively
    6. Managing databases created via dbaasapi (dbaascli) on a subset of the nodes (not recommended)
    • bkup_api
    bkup_api was replaced by dbaascli.

    • exacli
    exacli is the command line for getting storage cell metrics and diagnostics information on Exadata DB systems. 


    In this article, I will illustrate how you can patch the VM machine database system.

    Before running any command you should upgrade the cliadm with the latest patch version.  Upgrading this help you to support the latest features added to cloud services.

    Note: you do not need to worry about staging the patches, oracle will stage the patches in all the environments.

    Upgrade cliadm

    Once you execute the update-dbcli  status can be checked by running dbcli list-jobs command.

    
    
    [root@dbsdpl21 ~]# cliadm update-dbcli

    Upgrade database

    Upgrade commands need the database home-id, this can be obtained by running the dbcli list-DB homes. Make sure to clean up the database home folder and gain space before the upgrade.

    Note: I would recommend staying one patch level down (N-1), so you can apply the 19.17.0.0 patch for the database.

    
    
    [root@dbsdpl21 ~]# dbcli list-dbhomes

    Conclusion

    In summary, OCI is getting more mature day by day.  These new orchestration tools ease the life of oracle dba that spending on administration tasks like patching. 

    If you want to learn about server patching refer to my article on Oracle Cloud Infrastructure (OCI) - Part 2: OCI -VM Server and DB Patching.
